Complications and ultra-thin models: two time-honoured Audemars Piguet specialties meet in the Royal Oak RD#2. It has taken five years to develop the new ultra-thin 5133 caliber with perpetual calendar.

The challenge has been to re-engineer a three-storey movement into a single level, making it ultra-thin while combining and re-arranging functions to boost ergonomy, efficiency and robustness. This patented system features a recordshattering 2.89 mm central rotor. At just 6.30 mm, the redesigned case shaves almost 2 mm off the Audemars Piguet Royal Oak RD#2 Ultra-Thin Perpetual replica watch, making the Royal Oak RD#2 the thinnest selfwinding perpetual calendar on the market today.

Technical Specifications:
The case, in platinum, measures 41mm x 6.3mm. It has an AR-coated sapphire crystal, a sapphire display back, and it is water resistant to 20 meters.
